What weighs the most of a tonne of wood or a tonne of planks?

[Ters]

A tonne of planks, apparently. At least in Simutrans. There might be a very good reason for this, but it quite non-intuitive that two otherwise identical trains, transporting the same amount each of wood and planks according to the cargo load, don't weight the same.

In german it was a Festmeter once, which is higher for planks. Maybe ton is the wrong unit here.

A 'Festmeter' of wood also weighs the same, regarldess of its form (with one caveat). It only depends on the density of the wood itself. It is 1 m^3 of solid wood. Ie the total volume minus the volume of the gaps.

It would be korrekt for 'Ster', wich is the outside volume of a stack of wood. Standard conversion to 'Festmeter' is 0.7. Economically used 'Festmeter' usually also account for 20% loss during processing. Thus one stere lumber should equal about 0.56 m^3 planks (densest packing).

One cubic metre of pine, which pak64 plantations seems to grow, would weigh about 0.5 tonnes if there were no gaps. Using the standard conversion sdog provided, it would be 0.35 with gaps. To maintain the same weights of vehicles, their capacities must therefore be increased by a factor of about 2.4. Production and consumption rates must be adjusted likewise. I think the same could be done for planks. Apart from the immediate issue with each existing goods unit being worth less at the transition, the only big issue that I can see is station capacities.

Thanks, I learned a lot from this. Maybe renovation of plantations (with field) are indeed something which need to be done. (or Maybe even with normal trees, which are cutted down if to much supply is used).

There are some other goods as well where a tonne does not weight a tonne.

[prissi]

Not anymore, I hope

[Ters]

Perhaps not in the main part, but the food "add-on" lacks weights for everything, causing one tonne of grain to weigh 100 kg.

[prissi]

Thanks, I completely missed this.

According to the all knowing Internet, a cubic meter of grain weighs between 500 and 750 kg, depending on the type. Such a change would have quite an impact on existing games. As for the other bulk goods, coal would be between 1000 and 1500 kg, stone between 2500 kg and 3000 kg, sand about 1500 kg and iron ore about 2500 kg. Quite some differences this as well. In these cases, weight may be more of a limiting factor for vehicle capacity than volume.

[prissi]

Then lets stay with tons for bulk goods, and assume the weight is the limit.

[Ters]

If so, input factor at mills should be around 16 %. 1000 kg of flour should equals about 6 100 kg bags of flour. Now it would be more like 0.8 bags. Similar for other factories, but I haven't got any numbers for those.
